+A String is an indexed collection of Characters. In Cuis, Characters are Unicode Characters, each one associated with a numerical Unicode Code Point. In instances of String, all the Characters must be in the two Unicode blocks ("Basic Latin" and "Latin-1 Supplement", meaning the code point is <= 255.
+See also UnicodeString, that doesn't have this limitation.
+
+String support a vast array of useful methods, which can best be learned by browsing and trying out examples as you find them in the code.
+
+Here are a few useful methods to look at...
+	String match:
+	String contractTo:
+
+String also inherits many useful methods from its hierarchy, such as
+	SequenceableCollection ,
+	SequenceableCollection copyReplaceAll:with:
